At least one trolley (20) can be inserted into this incubation chamber, which is loaded with a plurality of egg trays (21) designed to hold numerous eggs (1). The eggs (1) are incubated under controlled environmental conditions. Furthermore, the incubator (10) comprises a door (11) for opening and closing the incubation chamber, as well as conveying means (40) that enable the automated transport of the at least one trolley (20) within the incubator (10). The invention also relates to a corresponding system and method.

Description

[0001] The present invention relates to an incubator for the automated incubation of eggs according to claim 1, a system for the automated incubation of eggs according to claim 12 and a corresponding method according to claim 15.

[0002] In industrial poultry farming, incubators are commonly used to incubate large numbers of eggs under controlled conditions. The eggs are placed in devices designed to hold a large number of eggs, such as special trolleys or racks that accommodate multiple egg trays, and these devices are placed inside large incubators where the eggs are incubated under controlled environmental conditions.

[0003] During incubation, it is desirable not only to monitor environmental parameters such as temperature, humidity, and CO2 levels, but also to check the condition of the incubated eggs. Relevant parameters for analysis include the egg's developmental and fertility status, as well as its sex. This information can be used to further optimize the incubation process.

[0004] Egg inspection is usually performed manually using backlighting (candling). Candling is a process in which the growth and development of an embryo inside an egg is made visible by a bright light source positioned behind the egg, allowing details to be seen through the shell. Although this method is considered reliable for assessing egg development in the early stages of incubation, it is labor-intensive, requires removing the eggs from the incubator—disrupting the incubation process—and proves very cumbersome in large-scale incubators where thousands of eggs are being incubated.

[0005] In principle, it would be highly advantageous to be able to monitor each individual egg in an incubator. At the same time, maximizing egg density in the incubator is desirable for optimizing incubation efficiency and throughput. However, increasing egg density in the incubator makes monitoring individual eggs more difficult and expensive. US 10,945,415 B2 describes an incubation tray that includes a variety of inspection modules assigned to different egg placements on the tray. Although this approach allows for individual egg monitoring, its application is limited due to cost—relying solely on these egg trays in an incubator would not permit an economically efficient incubation process and would require extensive maintenance.

[0006] Other approaches to placing measuring devices in the incubator are known. Some of the known solutions, which only require the installation of a limited number of detection devices in the incubator, do not allow for monitoring all eggs in the incubator. Other solutions that do allow monitoring of all eggs in the incubator are disadvantageous for economic reasons, as they are either very expensive due to the large number of detection devices required or take up a lot of space in the incubator, thus reducing capacity.

[0007] In light of the foregoing, one objective of the present invention is to further optimize the incubation process - in particular by increasing the number of eggs whose developmental status can be monitored during the incubation process and by reducing the required manual intervention - while at the same time maximizing the space utilization in the incubator and reducing the costs of the equipment required for the incubation process and monitoring.

[0008] This objective is achieved by an incubator for the automated incubation of eggs according to claim 1, a system for the automated incubation of eggs according to claim 12, and a corresponding method according to claim 15. Preferred embodiments of the invention are set forth in the dependent claims.

[0009] In particular, the problem is solved by an incubator for the automated incubation of eggs, preferably bird eggs, more preferably chicken eggs, comprising an incubation chamber in which at least one trolley can be accommodated which can be loaded with a plurality of egg trays designed to hold a plurality of eggs, and in which the eggs are incubated under controlled environmental conditions; a door for opening and closing the incubation chamber; and conveying means for the automated movement of the at least one trolley within the incubator.

[0010] The present invention increases the efficiency of the incubation process by providing the possibility of moving the eggs within the incubation chamber during incubation. Firstly, moving the eggs improves the incubation process itself, as varying environmental conditions in the incubation chamber are compensated for by the movement of the at least one cart. Potential local deviations in temperature, humidity, CO2 concentration, or other environmental parameters are essentially leveled out by the movement of the cart.

[0011] Furthermore, expensive and space-consuming equipment – ​​such as monitoring devices for checking eggs during incubation – can be used on a variety of carts. Carts to be inspected with such equipment can be moved towards the corresponding measuring device, thus eliminating the need for redundant measuring devices that would significantly increase the costs of equipping and operating the incubator.

[0012] Incubators are typically used for incubating freshly laid eggs, particularly poultry eggs. In the context of the present invention, the term "incubator" refers specifically to industrial incubators designed as climate-controlled chambers. An incubator as defined in the present invention is characterized by a closed incubation chamber that is insulated from the environment. Environmental conditions such as temperature, humidity, and / or CO2 concentration can be controlled within the incubation chamber. This makes it possible to simulate the incubation conditions of birds by replicating a desired incubation process through appropriate control of the environmental conditions in order to optimize the hatching process.

[0013] The incubation chamber is designed to accommodate a multitude of trays in which the eggs to be incubated can be stored. In the context of the present invention, the interior of the incubator is referred to as the incubation chamber. The incubation chamber can have a substantially cuboid shape, with its dimensions adapted to the dimensions of the trays so that trays can be arranged in a grid-like configuration within the incubator. For example, the dimensions of the incubation chamber in two orthogonal horizontal directions can be substantially integer multiples of the width and depth of a single tray. Thus, the incubation chamber can be selected such that its width is substantially twice the width of a single tray and its depth is four times the depth of a single tray.This would allow the placement of up to eight trolleys in a 2×4 grid, minimizing unused space in the incubation room.

[0014] The carriages referred to in the context of the present invention typically comprise a rigid frame structure having a rack-like structure and designed to accommodate a plurality of egg trays. The eggs to be incubated can be arranged on the egg trays in predetermined positions, for example, in recesses in the surface of the egg tray in which the eggs are partially received.

[0015] The conveying means for moving the at least one cart can be configured in many different ways, as detailed below. The conveying means must be capable of effecting movement—preferably (essentially) horizontal movement—of the at least one cart within the incubator. This allows the position of the at least one cart within the incubation space to be adjusted. The conveying means can be configured to push, pull, or tow the cart(s), transport the cart(s), and / or lift it to move it to a desired location and place it there.

[0016] According to the invention, the movement of the carts is automated. This is to be understood as any type of movement that does not require manual intervention by an operator of the incubator. The automated movement can be triggered automatically by suitable (electronic) control devices or by user interaction with a corresponding control device. In the context of the invention, the only crucial factor is that the automated movement does not require any manual intervention by a user in the incubation chamber.

[0017] According to a preferred embodiment, the conveying means comprise a robotic unit, preferably an automated guided vehicle (AGV).

[0018] Automated guided vehicles (AGVs) are a cost-effective and practical means of implementing the conveying equipment required for the present invention. An AGV is a portable robot configured to move along predefined markers—such as visible lines, wires, or natural patterns on the floor—or to use radio waves, cameras, magnets, or lasers for navigation. AGVs are used in industrial applications to transport heavy materials in large industrial buildings, such as factories or warehouses. AGVs represent an advantageous solution for moving carts within an incubator because they do not require excessive space, are easily integrated into an incubator, are simple to maintain, and exhibit high reliability.

[0019] To enable the movement of carts within an incubator, one or more AGVs can be used in the incubator.

[0020] Preferably, the at least one AGV is configured to move the at least one cart by moving underneath it, lifting it, and transporting it to another location. Egg carts, such as those commonly used in incubators, have a frame with legs, creating a space underneath the cart into which an AGV can freely access. In this embodiment, the AGV includes a height-adjustable deck designed to be raised when the AGV is underneath a cart, lifting the cart off the floor and supporting it on the deck. Once the cart is off the floor, the AGV can transport it to another desired location. Upon arrival, the deck is lowered to place the cart in the desired position. The AGV can then emerge from underneath the cart to transport another cart.

[0021] Alternatively, the AGV can be configured to pull the cart to a different location. In this case, it is preferable for the AGV to have a device for mechanically connecting to the cart so that it can pull it to another location.

[0022] In a potentially preferred embodiment, the conveying means comprise a rail-based conveying system. Preferably, the rail-based conveying system includes a plurality of rails in the incubation chamber and a rail-guided shuttle. The rail-guided shuttle is preferably configured to move along the rails and transport the at least one cart to another location by passing underneath it, lifting it, and carrying it. Furthermore, a plurality of cart supports are preferably provided in the incubator, arranged along the rails, to support a cart moved by the rail-guided shuttle.

[0023] A rail-based conveyor system is particularly easy to operate and maintain. Furthermore, the movement of the rail-guided shuttle is restricted by the rails, thus greatly reducing the likelihood of incorrect positioning of the carriages.

[0024] According to a further (preferred) embodiment, the conveying means comprise a conveying system mounted on the floor of the incubator and configured to convey at least one cart placed on the conveying system. In this embodiment, it is particularly preferable that the conveying system comprises at least one straight conveying element designed to move at least one cart along a substantially straight line, and / or at least one corner conveying element designed to change the direction of movement of the at least one cart.

[0025] Using a conveyor system as the conveying means has the advantage that existing trolleys can be used without requiring significant modifications to their configuration. Suitable types of conveyor systems include, but are not limited to, roller conveyors, belt conveyors, and roller floor systems. Particularly in the case of an essentially cuboid incubation chamber, it is preferable for the conveyor system to include at least one straight conveying element, preferably designed to transport the trolley(s) in a direction parallel to one of the incubator walls, and / or at least one corner conveying element designed to change the direction of movement of the trolley(s) by substantially 90°.

[0026] According to a further preferred embodiment, the conveying means comprise a cable-operated conveying system comprising at least one cable along which the carriage(s) can move, and / or a cable-operated shuttle configured to move the carriage along the cable(s).

[0027] Cable-driven conveyor systems represent another preferred means of implementing the conveying equipment, as they are easy to install and maintain, reliable in operation, and efficient. Preferably, the cable-driven conveyor systems are installed on the floor of the incubator and configured to pull the cart(s) at the bottom. Alternatively or additionally, the cable-driven conveyor systems can also be installed on the ceiling of the incubation chamber and configured to pull the cart(s) at the top.

[0028] It is also preferable that the incubator includes tilt adjustment devices with which the tilt angle of the egg trays on the trolley(s) in the incubator, in particular in the incubation room, can be adjusted.

[0029] It is desirable that the position of the eggs in the carts can be varied during the incubation process. To allow controlled movement of the eggs and / or controlled changes in the orientation and position of the eggs relative to the cart structure, the carts can be configured so that the orientation of the egg trays within the cart is adjustable. Preferably, the carts are designed so that the tilt angle of the egg trays is adjustable. The tilt angle refers to the angle between the surface of the egg tray (i.e., the plane on which the eggs rest) and an absolute horizontal. A tilt angle of 0° corresponds to an orientation in which the egg tray is parallel to the ground. A tilt angle of 90° corresponds to an orientation in which the egg tray is tilted into a vertical position, with the surface of the egg tray aligned parallel to gravity.The term "angle of inclination" is used below as a synonym for the angle of the egg trays on the cart(s).

[0030] The means for adjusting the tilt angle of the egg trays on the cart can be implemented by hinges or other mechanical means suitable for tilting the egg trays within the cart. The tilt angle can be adjusted mechanically by connecting the tilt adjustment devices to suitable adjustment devices on the cart frame, or alternatively electrically by providing electrically controlled adjustment devices—such as stepper motors—on the cart, which are controlled by the tilt adjustment devices. These terms are to be understood as synonymous in the context of the present invention.

[0031] Preferably, the tilt adjustment devices are integrated into a movable element of the conveying equipment, preferably the AGV, the rail-guided shuttle, or the cable-operated shuttle. This makes it possible to adjust the tilt angle immediately before, during, or immediately after the movement of the vehicle(s). Furthermore, this embodiment allows the conveying equipment and the tilt adjustment devices to be integrated into one and the same device.

[0032] The tilt adjustment devices can be implemented by mechanical means designed to interact with the corresponding adjustment devices of the carriage(s) to adjust the tilt angle. Alternatively, they can also be implemented by electronic means that send an electrical signal to electronic adjustment devices on the carriage.

[0033] According to another (preferred) embodiment, the tilt adjustment devices comprise a tilting device permanently installed in the incubator, configured to actively adjust the tilt angle of the egg trays on a cart located near the tilting device. Preferably, the tilting device is designed to actively adjust the tilt angle.

[0034] According to a further (preferred) embodiment, the tilt adjustment devices comprise a tilt feature permanently installed in the incubator, configured to passively adjust the tilt angle of the egg trays on a cart moving near the tilt feature. Preferably, the tilt feature is designed to passively adjust the tilt angle.

[0035] In the context of the present invention, an active adjustment of the tilt angle refers to a setting in which the tilting device performs a physical action - for example, a mechanical movement or the sending of a control signal - while a passive adjustment of the tilt angle refers to a setting in which the tilting feature does not perform a direct action, but effects the adjustment indirectly.

[0036] Examples of (active) tilt devices include an activatable drive or a control signal output. Examples of (passive) tilt features include physical features on the floor, wall, or ceiling of the incubation chamber, such as a bump or unevenness that adjusts the tilt angle when a cart moves near it.

[0037] The incubator according to the present invention may further preferably include a measuring unit 50, which serves to measure and / or monitor at least one variable of the incubation process and / or a condition of the eggs in the incubator. Preferably, the measuring unit is installed in a fixed position in the incubator. Alternatively, the measuring unit may also be designed as a mobile measuring unit that can be moved within the incubator or, even more preferably, between different incubators.

[0038] The measuring unit enables the measurement of at least one variable relevant to the incubation process. This includes the measurement of a variable that indicates the condition of the eggs in the incubator. The measuring unit can be configured to perform repeated measurements—preferably automatically—to allow for continuous monitoring of the variables in question.

[0039] Parameters relevant to the incubation process include temperature, humidity, egg weight, egg temperature, and CO2 concentration. Regarding the condition of the eggs in the incubator, it is preferable that the measuring unit be designed to measure and / or monitor at least one variable that indicates the health status and / or sex of an embryo within the egg. Suitable variables include optical parameters, such as the intensity of electromagnetic radiation at predefined wavelengths transmitted through the egg during examination.

[0040] In one embodiment, the measuring unit is installed in the incubator, preferably in a fixed position. Combined with the conveying system, this configuration provides an economically efficient solution to the problem of monitoring all eggs in the incubator during the incubation process. The eggs to be measured can be moved to the measuring unit using the conveying system. Thus, a single measuring unit is sufficient to monitor all eggs in the various trays of the incubator.

[0041] The object of the invention is further achieved by a system for the automated incubation of eggs, preferably bird eggs, more preferably chicken eggs, comprising at least one incubator as described above and at least one cart that can be loaded with a plurality of egg trays designed to hold a plurality of eggs. The cart(s) can be placed or are placed in the incubation chamber of at least one of the incubators. In one possible embodiment, the system comprises an incubator as described above and at least one cart.

[0042] The technical advantages achieved with the system of the present invention correspond to those achieved with the incubator described above. Aspects, features, and advantages described in the context of the inventive incubator also apply to the inventive system, and vice versa. The conveying means enable automated movement of the cart(s) within the incubator. This reduces the equipment required for the incubation process, as equipment such as tilt adjustment devices or measuring units can be provided in limited numbers and used for multiple carts within the incubator.

[0043] Preferably, the system comprises at least one robotic unit (as a conveying device), preferably an AGV, configured to move the cart(s) within the incubator. For the preferred configuration and operation of the robotic unit, please refer to the explanations given above.

[0044] Preferably, the system comprises a measuring unit configured to measure and / or monitor at least one variable of the incubation process and / or a condition of the eggs in the incubator. The combination with the inventive incubator, particularly with the possibility of automated movement of the cart(s), maximizes space utilization in the incubator and reduces the cost of the equipment required for the incubation process.

[0045] According to another (preferred) embodiment, the measuring unit is configured so that it can be placed (temporarily) next to or inside the incubation room.

[0046] In this embodiment, it is preferable for the measuring unit to be designed as a mobile unit that can be moved manually or automatically. This can further improve space utilization in the incubator, as the measuring unit does not need to be permanently located in the incubation chamber. Measurements regarding the fertility, health status, and / or sex of the eggs may not be required throughout the entire incubation period. If the measuring unit is designed as a mobile unit, it is possible to use one measuring unit in several incubators, which further improves the system's cost-effectiveness. If the measuring unit is configured as a mobile unit, it is preferable for the system according to the invention to comprise two or more incubators.

[0047] The measuring unit is preferably configured so that it can be placed next to or inside the incubation chamber. The measuring unit is positioned to ensure access to the cart(s) in the incubation chamber. This allows the measuring unit to perform measurements on the eggs in the incubator.

[0048] In one possible embodiment, the (mobile) measuring unit is configured to be placed in an open door of the incubator(s). In this embodiment, it is preferable for the system to further include an isolation unit designed to be placed next to the measuring unit in order to isolate the opening provided by the open incubator door from the environment. This ensures that the incubation process is not disturbed by the use of the measuring unit.

[0049] Alternatively or additionally, the incubator(s) may include a removable wall section or flap that provides access to the incubation chamber. The measuring unit is configured to be positioned next to an opening in the incubator(s) formed by the removable wall section or open flap, allowing measurements to be taken on the eggs on the trolley(s) in the incubation chamber. In this embodiment as well, the system may include an isolation unit positioned near the measuring unit and the opening of the incubator(s) to isolate the opening.

[0050] The objective of the present invention is further achieved by a method for the automated incubation of eggs, preferably using an incubator and / or system described above. The method comprises the steps of placing at least one trolley, which can be loaded with a plurality of egg trays designed to hold a plurality of eggs, into an incubation chamber of an incubator; and moving the trolley(s) automatically within the incubation chamber during the incubation process.

[0051] The technical advantages achievable with the method of the present invention correspond to those achieved with the incubator and system described above. Aspects, features, and advantages described in the context of the inventive incubator and system also apply to the inventive method, and vice versa. In particular, any (automated) task for which the inventive incubator(s) and / or the inventive system is configured can be used as a process step in the inventive method, and vice versa. Preferably, the inventive method is carried out using an inventive incubator and / or system as described above.

[0052] It is preferable that the procedure includes placing a large number of eggs on the trolley(s) prior to incubation. The eggs can be placed on the trolley(s) before or after being introduced into the incubation chamber.

[0053] Preferably, the method involves introducing a large number of trolleys into the incubation chamber of the incubator and automatically moving the trolleys during the incubation process. Increasing the number of trolleys in the incubation chamber improves the throughput of the incubation process.

[0054] Preferably, the automatic movement of the carriage(s) occurs in a cyclical or circular manner. Preferably, the position of the carriage(s) is varied along a closed loop. This ensures that the carriage(s) undergo regular measurements and / or tilt angle adjustments without requiring the tilt adjustment devices or measuring units within the incubator to be moved. Instead, the carriage(s) is transported to the tilt adjustment devices and / or the measuring unit on a cyclical basis.

[0055] In a preferred embodiment, the method comprises introducing a plurality of carts into the incubation space, such that at least one - preferably exactly one - space or slot remains free for a cart, and moving the carts in the incubation space such that their positions are permuted along a closed loop.

[0056] Leaving at least one space, preferably exactly one, empty in the incubator maximizes space utilization. With at least one space left empty, the carts can be moved cyclically within the incubation space by sequentially permuting their positions. The movement of the carts resembles that of a sliding puzzle, where one empty slot is present and all pieces are successively moved into this empty slot.

[0057] It is further preferable that the method includes adjusting the tilt angle of the egg trays of the cart(s) during the incubation process, preferably automatically and depending on the position of the cart(s). Combined with the cyclical permutation of the cart positions, this ensures that each cart regularly comes within range of the tilting device. Thus, the tilt angle of all carts in the incubator can be adjusted at regular intervals using only one tilt adjustment device.

[0058] According to a further (preferred) embodiment, the method comprises measuring and / or monitoring at least one variable of the incubation process and / or a state of the eggs in the incubator during the incubation process. Analogous to adjusting the tilt angle, a measuring unit that performs the measurement and / or monitoring can be attached to a fixed position in the incubation chamber. A cyclic permutation of the cart positions makes it possible to perform regular measurements on each cart during the incubation process without requiring multiple measuring units.

[0059] The above-mentioned and further features and advantages of the present invention are explained below with reference to a detailed description of preferred embodiments of the invention and the accompanying drawings, in which: Fig. is a schematic top view of an incubator according to a preferred embodiment of the invention; Fig. is a schematic side view of the incubation space in an incubator according to a preferred embodiment of the invention; Fig. is a schematic top view of an incubator according to a further preferred embodiment of the invention; Fig. is a schematic side view of the incubation space in an incubator according to the embodiment of Fig. ; Fig. is a schematic top view of an incubator according to a further preferred embodiment of the invention; Fig. is a schematic side view of the incubation space in an incubator according to the embodiment of Fig. ; Fig. is a schematic top view of an incubator according to a further preferred embodiment of the invention; Fig. is a schematic side view of the incubation space in an incubator according to the embodiment of Fig. ; Fig. is a schematic side view of an incubator according to a further preferred embodiment of the invention; Fig. is a schematic top view of a system for the automated incubation of eggs according to a preferred embodiment of the invention; Fig. Illustrate a cyclic permutation of the carts in an incubator according to a preferred embodiment of the invention.

[0060] Fig. Figure 1 shows a schematic top view of an incubator 10 according to a preferred embodiment of the present invention. The incubator 10 has a substantially cuboid shape, with the incubation chamber being divided by three incubator walls on the left, right, and top sides. Fig. is limited, as well as by a door 11 on the lower side of Fig. The door 11 is schematically represented as a door extending across the entire width of the lower side of the incubator 10. In alternative embodiments, the door 11 may also cover only a portion of the lower side of the incubator 10 or be designed as a hinged double door.

[0061] Inside the incubator 10 are a multitude of trolleys 20. In the embodiment of Fig. Nine trolleys 20 are housed in the incubation chamber of incubator 10. Trolley 20 in the upper right corner of incubator 10 is shown holding a large number of eggs 1.

[0062] Fig. shows a schematic side view of the incubation chamber of incubator 10. Fig. Of the nine trolleys 20 housed in the incubation room, five are visible from the side. The four trolleys 20 on the left are empty, while the trolley 20 on the right is filled with a large number of eggs 1. As in Fig. As can be seen, the eggs 1 rest on egg trays 21, which are located in carriage 20 on the right side of Fig. are loaded.

[0063] Alone Fig. The illustrated carriages 20 comprise a (fixed) carriage frame 22, which gives the carriage 20 a rigid structure. A tiltable carriage frame 23, which contains devices for holding a plurality of egg trays 21, is hinged to the (fixed) carriage frame 22. The tilting angle of the egg trays 21 can be adjusted by tilting the tiltable carriage frame 23. Fig. The tilting carriage frames 23 are inclined such that the egg trays 21 have a tilting angle of approximately 45°.

[0064] The tilt angle of the egg trays 21 on the trolley 20 is adjustable by means of a tilt adjustment device 30, which is located in Fig. The tilt adjustment devices 30 are installed at a fixed location on one of the side walls of the incubator 10 in the incubation chamber. Although not shown in detail in the drawings, it can be assumed that the tilt adjustment devices 30 are configured to adjust the tilt angle of the egg trays 21 on a trolley 20 that is moved close to the device. In the embodiment of Fig. A carriage 20 is moved into position next to the tilt adjustment devices 30 to allow them to adjust the tilt angle. The adjustment can be performed actively, for example by tilt adjustment devices 30 which include mechanical means that interact with the carriages 20 to adjust the tilt angle.

[0065] The incubator according to the present invention comprises conveying means for moving the trolleys 20 housed in the incubation chamber. Fig. The means of support are not explicitly shown. It is obvious that the inclination adjustment devices 30 in the embodiment of Fig. are most effective when the carriages 20 can be moved close to the tilt adjustment devices 30. Fig. Each figure shows a top view or side view of an incubator 10 according to an embodiment of the present invention. Common features with the embodiment of Fig. For the sake of brevity, these points will not be explained again.

[0066] The incubator 10 in Fig. Figure 40 shows conveying means, which in this embodiment are realized by an AGV 41. The AGV 41 is configured to move within the incubation space. In particular, in Fig. It is clearly visible that the FTS 41 is moving beneath trolley 20. The FTS 41 has a deck designed to rise vertically, lifting trolley 20 beneath which it is positioned. The lifted trolley 20 can then be transported by the FTS 41 to another location within the incubation room.

[0067] The incubator 10 with the FTS 41 represents an embodiment of the present invention. Analogously, a system that combines the incubator 10 according to Fig. / 1b and the FTS 41 comprises an embodiment of the invention.

[0068] Fig. Figure 1 shows a further embodiment of the present invention. In this embodiment, the conveying means 40 are implemented by a rail-based conveying system. As in Figure 2 Fig. As can be seen, the rail-based conveying system comprises a multitude of rails 42 arranged on the floor of the incubator. The system also includes a rail-guided shuttle 44 configured to move on the rails 42 and position itself under the trolleys 20 in the incubator 10 to transport them to another location by passing underneath, lifting, and carrying them. The operation of the rail-guided shuttle 44 corresponds to that of the AGV 41 from Fig. Furthermore, the rail-based conveying system preferably comprises a plurality of carriage supports 43 arranged along the rails, which serve to support a carriage moved by the rail-guided shuttle 44 or to secure it against tipping over. These carriage supports 43 can also be referred to as carriage position holders.

[0069] Fig. Figure 1 shows a further embodiment of the invention in which the conveying means 40 are realized by conveying elements 45. These conveying elements 45 are located on the floor of the incubator 10. The in Fig. The arrows shown indicate the conveying direction of the respective elements. The conveying elements 45 comprise straight conveying elements 45a, which are designed to move carriages 20 along a straight line parallel to the walls of the incubator 10, and corner conveying elements 45b, which are designed to change the direction of movement of the carriages 20 from a direction parallel to the long sides of the incubator 10 to a direction parallel to the short sides of the incubator 10. This embodiment allows for very flexible movement and positioning of the carriages 20 within the incubator 10.

[0070] Fig. Figure 1 illustrates a further embodiment of the invention in which the conveying means 40 are realized by a cable-driven conveying system 46. The cable-driven conveying system 46 comprises a cable 46a which is Fig. The system is installed on the floor of incubator 10 – alternatively, it could also be installed on the ceiling. Furthermore, the system includes a cable shuttle 46b configured to pull or move the trolley 20 along the cable 46a. To allow the trolleys 20 to be positioned throughout incubator 10, several cable 46a can be arranged along the rails 42 in the Fig. or the conveying elements 45 in Fig. similar.

[0071] In the embodiments of Fig. The tilt adjustment devices 30 are shown schematically at a location adjacent to the door 11 of the incubator 10. However, the tilt adjustment devices 30 can also be provided at a different position in the incubator 10. In combination with the conveying means 40, the incubators 10 according to the present embodiments can be equipped with a reduced number of tilt adjustment devices 30 – for example, it is possible to equip the incubator 10 with only one tilt adjustment device 30, which is used to adjust the tilt angle of all trolleys 20 in the incubator 10 by moving the trolleys 20 near this device using the conveying means 40.

[0072] The tilt adjustment devices 30 in Fig. The tilt adjustment devices 30 are schematically depicted as a feature installed on a wall of the incubator 10. However, they can also be part of the conveying equipment 40 or an internal component of the trolleys 20. In particular, the tilt adjustment devices 30 can be designed as a feature of the AGV 41, the rail-guided shuttle 44, or the cable-operated shuttle 46b. In this case, the tilt adjustment devices 30 are configured to adjust the tilt angle of a trolley 20 located above the AGV 41, the rail-guided shuttle 44, or the cable-operated shuttle 46b—in particular, the device can adjust the tilt angle of a trolley 20 being moved during transport by one of these conveying equipment.

[0073] The tilt adjustment devices 30 can also be implemented by an element that adjusts the tilt angle of a carriage 20 as it moves near the device. For example, a raised or recessed area in the floor of the incubator 10 can serve as the tilt adjustment device 30. In this case, the carriage 20 is configured to change its tilt angle as it moves over or past the raised or recessed area. The tilt angle adjustment can be achieved either mechanically or electrically. In the latter case, the tilt adjustment devices 30 send a control signal to the carriage 20, which is configured to receive the signal and adjust the tilt angle using, for example, stepper motors.

[0074] The incubators 10 according to the present invention may further preferably comprise a measuring unit 50, which is not explicitly specified in Fig. The measuring unit 50 can be permanently installed in the incubator 10 – for example, near or in the same location as the tilt adjustment devices 30 – so that trolleys 20, which are moved near the measuring unit, can be subjected to measurements of parameters relevant to the incubation process. For example, parameters indicating the condition of the eggs 1 in the incubator 10, such as the intensity of optical signals transmitted by the eggs 1, can be measured. Such parameters can be used to monitor and assess the fertility and health of the eggs 1, as well as the sex of an egg 1.

[0075] Fig. Figure 1 shows a schematic top view of a system for the automated incubation of eggs 1 according to a preferred embodiment of the present invention. For clarity, the conveying means 40 are shown in Fig. not explicitly shown. In addition to the elements already discussed – in particular the incubator 10 with the doors 11, the trolleys 20 for holding the eggs 1, the tilt adjustment devices 30 and the conveying means 40 – the system comprises in Fig. furthermore a measuring unit 50, which in this embodiment is designed as a mobile measuring unit and can be moved close to the incubator 10 so that it comes into contact with the incubation chamber.

[0076] In the embodiment of Fig. The measuring unit 50 is moved towards an opening in the incubator 10 created by opening the door 11. To prevent any negative effects on the incubation process, an isolation unit 51 is provided, configured to be placed near the measuring unit 50 and to isolate the opening created by the open door 11 from the environment. The trolley 20 in the lower left position of the incubator 10 is located near the tilt adjustment devices 30 and the measuring unit 50 and can therefore be subjected to both tilt angle adjustment and measurement of the eggs 1.

[0077] The present invention improves the space utilization of incubators, since only a limited number of tilt adjustment devices 30 and / or measuring units 50 are required for all trolleys 20 in the incubator 10. To ensure that all trolleys 20 in the incubator 10 can be regularly subjected to tilt angle adjustment and / or measurement or monitoring of the relevant parameters, the automated movement of the trolleys 20 preferably occurs cyclically, so that each trolley 20 is repeatedly and regularly moved close to the tilt adjustment devices 30 and / or the measuring unit 50.

[0078] Fig. illustrates a method for the automated incubation of eggs according to an embodiment of the present invention. As in Fig. For the sake of clarity, the funding figures (40) have been omitted. The movement of the wagons caused by the funding figures is represented by white arrows.

[0079] Fig. Figure 1 shows an initial configuration of incubator 10 with nine trolleys 20. The trolley 20 in the lower left corner is located near the tilt adjustment devices 30 and the measuring unit 50 and is subjected to tilt angle adjustment and / or measurement. To maximize space utilization in incubator 10, the incubation chamber is filled with trolleys 20 in such a way that only one slot remains free.

[0080] To ensure that all trolleys 20 in incubator 10 are regularly subjected to tilt angle adjustment and / or measurement, the automated egg incubation procedure includes a cyclic permutation of the trolley positions 20 in incubator 10. The cyclic permutation of the trolley positions occurs in a movement pattern resembling a sliding puzzle. This is described in Fig. illustrated.

[0081] In the Fig. In the configuration shown, the carriage 20 in the lower left corner is moved to the free slot in the lower right corner of the incubation chamber. This frees up the slot adjacent to the tilt adjustment devices 30 and the measuring unit 50. As shown in Fig. As shown, the carriage 20, which is located directly above the free slot in the lower right corner, is moved into this free slot, thereby clearing the space above the slot adjacent to the tilt adjustment devices 30 and the measuring unit 50. All carriages 20 on the left side of the incubation chamber are each moved down one slot, which in Fig. The configuration shown results. As in Fig. As can be seen, cart 20 in the upper right slot of the incubation chamber is moved to the free slot in the upper left corner, thereby freeing up the upper right slot of the incubation chamber, as shown in Fig. As shown. All trolleys 20 on the right side of the incubation room are each moved up one slot, so that the slot in the lower right corner is freed and the configuration is from Fig. is restored - with the result that each car was shifted 20 times one position counterclockwise.

[0082] This cyclical change of the trolley positions in the incubation chamber represents a cyclical variation of the trolley positions along a closed loop. During the incubation process, each trolley 20 is successively moved to an adjacent position, so that the positions of all trolleys 20 are cyclically permuted. This ensures that each trolley 20 is regularly and periodically positioned near the tilt adjustment devices 30 and / or the measuring unit 50. Using this method, each trolley 20 can be subjected to a tilt angle adjustment and / or a measurement (of the eggs 1 on the trolley 20) at regular intervals, requiring only one tilt adjustment device 30 and / or only one measuring unit 50.

[0083] Thus, the present invention enables automated incubation of eggs 1 in an incubator 10 with optimized space utilization and throughput, using a minimal amount of equipment.
